Hello. Although you have not shown the passage you are referring to, we can confirm that the short story, in general, creates a portrait of Usher as someone nervous, anxious and with a strong hypochondria and sensitivity.

Explanation:

This question is about "The Fall of the House of Usher" a short story written by Edgar Alan Poe. When Poe wrote this story, little was known about psychological illnesses such as acute anxiety and hypochondria, but the short story shows Usher with strong symptoms of this disease. This is because the character has an acute and unjustifiable concern, in addition to considering his physical condition much worse than he really is and believes that he has diseases that he may not even have.
